There is a trading forum in which to you can ask for one. You shouldn't be asking for one if you don't have anything decent to trade for it. In all honesty, no one gives away a shiny Axew for nothing in return except for people who are giving away reject ones or are cleaning out there games. If you have something worth while you should post that along with your request. It can't be anything common or event. Many people expect a shiny in return.
